. in its correct operative position also to provide an apron or belt with means auiriliary'to the regular connection between-the ends, for making a temporary oremergency fastening for connecting the ends of the web; also to provide a method. of forming an improved connection. between two. web ends; also to improve the construction of apron connec tions in other respectshereinafterspecified.

Inconstructions as heretofore employed for connectingthe ends-of such-websfthe connections ordinarily extended to. the side edges of thcaweb, and consequently, when an edge of theweh rubbed against flanges or other guide devices formaintainingthe apron or beltin correct operativeposition, the ends of the connecting means would at times catch on suchflanges orguardsresult ing in the ripping or tearing'of theconn'ecting means and consequent ravelli-ng'of the; apron or belt at theedg'es, This ripping would sooirextend farther crosswise of the WILLIAM J.'sIMrSo1v, 0F VERETT, MASSACHUSETTS, :AsSreNomBY MESNn-AsSIsiL CONNECTION'FOR THE-ENDS (JLE V TJEBS 1931.

web until the same became useless, and the ravelling wouldfform wadsoffabric which would interfere with; the proper functioning of theweb. I 1 V In accordance with myinvention, the cor-. ner portions 7 of, the ends of'the web are folded back on the web at an angleof approximately{l5 to fthe lengthjofi the web. Inwebs ofthis'kind, thefsides of the-webare usuallyselvage edges, and the ends of the web, which are to, be secured togethenare cut 7 edges, and consequently, are apt to ravel; By folding the cornerportions over a'sdescribed, they have their cut edges 8 arranged at a distance from theside edges of the web,

where theyare not exposed contact with the usual guides or flanges, ,whichbooperate with thesides of the web tokeepethe web in 1 its operative position. These, corner por therein; j

webf may be'effected by any suitable securing device or lacing. In the particular construe:

tion shown, a ,wellknown form OflaCing is ing the two web ends so that the loops of one web -end lie between the loopsof the other web ends, alljthese loops can beconnected Iv belt. This fastening for theends of the web extends only to the folded corner portions 7;

tions, are secured 'in their 'folded' positions byany suitable means Preferably, groin-f mets 9 are employed for this purpose, therel 'atively thin metal heads or disks of which:

lie in close contact with the opposite faces oflthe web.'.. These grom'mets,*in the con-1 V structionshown, have holes: or, apertures 1 0 The securing togetherof the ends of the employed, including the usual inetalor wire loops 11, the outer ends of which are pointed i and bent over to form hooks which are driven f I intothe web from both-faces thereof. The" loop .portions of these belt-hooks [of h each; web end are all in alinement, and byarrangandthe connecting rods 14 terminate at conv siderable distances from the edges of the web, and are,;therefore,notapt to come-into con tact with guides or flanges for keeping'thc edges 8 of the corner portions 7'.

In order-to makea secure connection be-- tween. the fastening devices and the; web, the belt hooks 11 are preferably fastened to a doubled-over portion of the web, and for this purpose the web ends may be cut" asshown in Fig. 4, thus cutting away substantially square portions at opposite sides of'the end of the web and leaving a projection 16. in the intermediate portion of' each web end to be connected, and this end. flap or extension 16 is then folded backwardl'y against a face of the web... Preferably, this end extension or flap 16 is folded against the same face of the web as are the corner portions 7' and the edges 17 of the extension 16 will, therefore, lie in substantially abutting relation to the This. arrangement results. in a double thickness of the web at. the end portions thereof, and avoids overlapping of" the extension 1.6. with the corner portions 7 which would form anexcessive thi cknessof material at the overlapped porti ons-.. The belt fastening devices 11' can, consequently, 'be secured. through two. thicknesses of web.

The use of'grommets for securing the corners of the web in place is. desirable, since.

when secured in place, the opposite faces of the grommets lie closely to the surfaces of the weband the edges are not sharp so thatwhenthe web is used as an apronin an ironing machine, these grommets have no tendency tocut the work which is being ironed. The grommets have the further advantage that.

they can be used. to form a temporary oremergency connection between two web ends,

' particularly, if the regularconnection beconnected by means of the wiresv or cables 19 to anold apron, so that the new. apron may be drawn through the ironing machine by the operation of the machine. This emergency connection may, of course, also be used when for any reason-the other connection beof the. web. toravel. The recesses in the sides of the web, formed by folding over the corner portions, also terminate in folded-over edges 18 of the corner portions of the web, and consequently, as these folded-over portions contact with guides or flanges for guiding the web in its travel, these folded-over portions offer a high resistance to Wear. By locating-the ends of the connecting rods or wires 1% Well within: the recesses formed byfolding the corners of the web, these connecting members are guarded: againstdamageeresulting from contact with and rubbing against flanges or othermeans for guiding the traveling web. 7 i

,I- claim as 'myinvention 1. A web havinga cutend having thecorners at said end folded inwardly against the web at an angle to thelongitudinal. end and to the edges ofthe web, so that the cut edges of the corners lie at a distance from the edges ofthe web, and connecting meanssecured to the end of the web between said folded over corners and terminating at a distance from the edges of the'web and adapted forconnection to anotherweb end.
